GAP Analysis Predicted Distribution Map

American Wigeon (Anas americana)

Species Code: ANAAM

Legend:

= Marginal Habitat

Breeding Range Map
The green area shows the predicted habitats for breeding only. The habitats were identified using 1991 satellite imagery, Breeding Bird Atlas (BBA), other datasets and experts throughout the state, as part of the Washington Gap Analysis Project. Habitats used during non-breeding months and migratory rest-stops were not mapped.

Breeding Status and Distribution

This species is uncommon in freshwater ponds and wetlands of lowland eastern Washington, including the central Columbia Basin, north to the Okanogan valley (not in the Methow valley), and east to the Pend Oreille River valley. More common in the northern portions of this range, and rare to absent in southeastern Washington and the Palouse. Also rare in the lower Columbia Basin, including Yakima, Klickitat, and Benton Counties. On the west side, a very rare and local breeder in Snohomish and King Counties (in the Everett and Kent areas, respectively), and possibly other sites in the southern Puget Trough, and at Cat Lake in Clallam County.

Model

Good habitat in core zones included all freshwater bodies and wetlands in eastern Washington in the Central Arid Steppe, Three-tip Sage, and Ponderosa Pine zones in Okanogan, Ferry, Stevens, and Pend Oreille Counties only.

Comments

The majority of this specie's range is north of Washington. It enters the state, primarily in the northeast. Most of the Columbia Basin and all of western Washington were excluded from the model because of the scarcity of records, and because many of the records may actually be from migrants pairing in these areas but breeding elsewhere.
